SPECIFICATION iorming part of Letters Patent No. 391,809, dated October30, 1888.

Application filed March 10, 1888.

To aZZ whom, it may concern:

Be it known that I, J OHN EDDY Mrcma citizen of the United States,residing at Portsmouth,in the county ofScioto and State ofOhio, haveinvented certain new and useful Improvements in a Hydraulic Motor; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

, My invention relates to hydraulic motors and provides a noiselesseconomical impact water-wheel adapted to mechanical and domestic uses.

The object of my invention is to construct a watenwheel in such a mannerthat the full amount of power residing in a given supply of water may beutilized, and to regulate the amount of water needed for agiven amountof power and by the arrangement of its parts to render it noiseless andclean in operation, so that it may more particularly be used in thedomestic arts. I attain these objects by constructing a metal casingintwo parts provided with flanges,which permit of their being boltedtogether. The lower part is made with feet, on which the whole maysiand,and has asupply-chamber extending the entire distance around thecasing under the flange, the said supply-chamber communicating with theout side by an inlet pipe and having nozzles communicating with theinside of the turbine, through which the water issues from thesupply-ring in streams, impinging on the buckets carried by the wheel.The nozzles which lead the water to the buckets are provided withstop-rods having screw threads and extending to the outside of, thecasing. Each nozzle having a separate stoprod, it will be easily seenthat any one nozzle may be closed or opened at will, and as the watercannot issue except by these nozzles a greater economy is attained,while the full amount of power is used.

In the accompanying drawings, forming a part of this application, and inwhich like let ters of reference indicate like parts, Figure 1 is anoutside view of the impact water-wheel. Fig. 2 is a perspective viewshowing the interior. Fig. 3 is asectional view showing thesupply-chamber, the stop-rods, and the wheel provided with buckets; andFig. 4 is an enlarged view of part of the supply-chamber.

A represents the lower part of the outer casing; B, the upper part; B,bolts for holding together the upper and lower parts of casin 0, thewheel; I), the cone shaped buckets on the wheel; E, the stop-rods,having screwthreads cut on them; E, the heads of the stop rods to beactuated from the outside; E jamnut; F, the inlet-pipe bringing water tothe circular supply-chamber; G, nozzles on the inside of thesupply-ring, closed by the stoprods; H,theshaft,rigidly attached to thewheel; H, hollow core in shaft to oil bearings; K,beltpulley; L, step toreceive the end of the shaft; llLapron to protect oil-box; N, thewaste-pipe;

O, bracket providing theupper bearing of shaft, and P boss or shoulder.

The casing may be constructed of cast or i malleable iron and has acircular supply-chain ber, G, from which the water issues by the nozzlesG, the direction of which should be so as to direct streams of wateragainst the buckets at right angles to their faces. The stoprods havepointed ends, which it accurately into the nozzles,and their shanks areprovided with screw-threads engaging in female threads made in aperturesin the outside of the casing. Their heads are formed flat to facilitatetheir being turned by the hand and their being adjusted from theoutside. To prevent anyout side leaking from these threadedapertures,the casing is made with bosses 1 P and the stop rods areprovided with jam-nuts Fr, which may be set up tightly against thebosses, thereby forming tight joints. The wheel may be made of anysuitable material and is attached to the shaft H, which has bearings inthe step L and in the bracket 0. The central opening to the shaftpermit-s of the lubricating of the lower bearing. The pulley is placedunder the bracket 0 for apparent mechanical reasons. The buckets D D areconstructed cone-shaped and are attached to the wheel in any wellknownmanner. Instead of cones, any other shaped buckets may be used but theformer are better, as their form presents a larger surface to theimpinging streams of water.

For putting the casing together, I provide 2 serene bolts and nuts B,which,with a slight packing, will allow of the formation of a tightjointbetween the upper and lower halves of the casing,

The impact water wheel having been connected to whatever it is intendedto actuate by means of a belt running over the pulley K, the operationis as follows: The water having been turned on through the inlet-pipe F,the whole of the supply-chamber will be filled with it. By unscrewingone of the stop-rods the water will issue by the nozzle that was closedby its point,and,impinging on the buckets carried by the wheel, willrotate it, and the quantity of water by this means can be graduated to va greater or less amount through each nozzle. Should the wheel remainstationary on opening one of the nozzles, it will be necessary tounscrew another stoprod and continue opening others until the desiredamount of power is obtained. The water,after impinging on the bucketsand rotating the wheel,will escape by the waste-pipe N, to which may beattached a rubber hose or any convenient receptacle. To lubricate thebearings, a few drops of oil may be introduced into the core of theshaft, from which it will descend to the lower bearing in the step L,theapron M tending to prevent the water from getting to an oil-box, whichmay be added to the said lower bearing.

The advantages possessed by my turbine are the greater facility forobtaining the necessary power required for the work it has toaccomplish. For instance, should it be desired to run a lightsewing-machine with it, and should it be necessary to economize theamount of wa ter, it will be readily seen that a less number of nozzlesmay be opened than in the case .of the heavier machine, requiring thefull force of water obtainable through the supply-pipe. Anotheradvantage is the ease with which the water-supply may be regulated andthe necessary amount allowed to impinge on the buckets, thenoiselessness of the movement and its general cleanliness adapting it tohousehold purposes.

I do not limit myself to the form of buckets shown in the drawings andherein described, nor to the number of nozzles and stop-rodsp I am awarethat impact water-wheels have been constructed with a ring-supply, andalso with a number of apertures between the ringsupply and the wheel;but the nozzles provided with threaded stop-rods and the circular supplychamber having no other outlet than the nozzles I believe to be new.

What I claim as my invention is An impact water-wheel having the lowersection of a flanged case provided with an annular inclosedsupply-chamber and internal radial nozzles, the adjustable stop-rodsadapted to close or regulate the influx of water through said nozzles,apipe for supplying water to said annular chamber, a series ofcone-shaped impact buckets arranged on the periphery of a rotative disk,a hollow shaft therefor, and a coveringsection, all as specified.

In testimony whereof I ai'fix my signature in presence of two witnesses.

JOHN EDDY MICK.
